Zamboanga Peninsula is an administrative region in the Philippines, designated as Region IX. It consists of three provinces including four cities and the highly urbanized Zamboanga City. The region was previously known as Western Mindanao before the signing of Executive Order No. 36 of 2001. The city of Zamboanga was designated as the regional center until Pagadian was designated as its new regional center, although Zamboanga City remains the region's cultural, commercial, economic, and educational center.

Cebuano is an Austronesian language spoken in the southern Philippines. It is natively, though informally, called by its generic term Bisayâ or Binisayâ and sometimes referred to in English sources as Cebuan. It is spoken by the Visayan ethnolinguistic groups native to the islands of Cebu, Bohol, Siquijor, the eastern half of Negros, the western half of Leyte, and the northern coastal areas of Northern Mindanao and the eastern part of Zamboanga del Norte due to Spanish settlements during 18th century. In modern times, it has also spread to the Davao Region, Cotabato, Camiguin, parts of the Dinagat Islands, and the lowland regions of Caraga, often displacing native languages in those areas.
